The bibtex package

This package allows parsing, formatting and processing of BibTeX files.
BibTeX files are databases for literature for the natbib package
of the LaTeX typesetting system.

The package contains two examples:

The first example demonstrates the BibTeX parser
by generating a publication overview from a .bib file.

The second example demonstrates the BibTeX generation
by producing a large .bib file from the tar archive
that cabal-install downloads to your local cabal directory.

Both examples will be build as stand-alone executable
when running

cabal install -fbuildExamples bibtex

For the first example see the publications directory of this package.
You can start the program and build an example document by running

make pubs

Technically the program generates a list of custom \nocite commands
for the LaTeX package multibib.
You can add the custom bibtex field subtype to BibTeX entries
for more detailed categorization of an entry.
See publications/publications.bib for examples.

The second example can be executed using

make hackbib

The file hackage.bib is written to the hackage subdirectory.
The hackage-bibtex program
reads an uncompressed tar archive from standard input
and writes the result bibliography file to standard output.

Note that hackage.bib exceeds some limits of standard BibTeX and LaTeX:
There are currently much more than 5000 versions of packages,
the maximum my BibTeX can handle at once.
That is, you can use the bibliography file,
but you cannot cite all entries with \nocite*.
If there are more than 26 uploads by the same author in a year,
the BibTeX style alpha generates identifiers including curly braces
which interacts badly with LaTeX's handling of them.
If you reduce the Bibliography file to 5000 entries
and try to generate an overview of all entries with \nocite,
then pdflatex hits its limits:
